T0 all whom il may concern:

Be it known that I, ANDREW P. NICHOLS', a citizen of the :United States, residing at Seattle, in the county of King and' State of VVashngton, haveinvcnted certain new and useful Improvements in Electrical lVater- Heaters, ofvwhich the following is a speciication. f r

This linvent-ion relates `elttirical water heeters.- the object of the. invention being to provide a compact appliance o'f Athis character by lwhich watercau be quickly and effectively heated.

In the drawings accompanying and forming vpart ofthe present specication I show in detail vone convenient form of embodif: ment ofthe invent-ion which toenable those skilled in the art to practice said invention will be set forth fullyin the following description, while the novelty of the invention 'will be included in the claims succeeding said description. YFrom this observation' it will be apparent thatI do not restrict my self.to suchshowing; I` may .depart there- 4from in several respects within the scope of .my-invention covered in said claims.v Referring to4 said-drawings,Y Figure -1` 1s ,a -sectfinialjj'side elevation; of an electrical. wateriheater 'including my invention.

The device preferably embodies .inits cn- .strnction a member having means for the passage of water, and while this member may vary radically as to material and 40l shape, it is preferably made from some suitable non-conducting or insulatin material such as porcelain. A member suc as satis factorily answers my requix'ements,: is that denoted in-:aener-al way by 5, being shown A5 as c lindrica. lVhile the non-conducting may be disposed in any *suitablel way. it is guierally'set vertically7 and it i'sl shown as hafvmg'two ducts .G and 7 -extend- Y' 'ing lonnitndi'nallythereof, the-duct .ticonfV 0 stitnting hat might be considerezhigin inletA uct,.'whxle tl1e duct T'presentsan' out-let fifig.

duct. In addition to these ducts the inem#- ber 5 has other ducts 8 of which there may bc any suitable number. There is practically no difference in construct-ion between the ducts' 6, 'I and 8. In the present case and as will hereinafter appeanhowever, the ducts 8 are adapted to receive bends or coils connected with'the first or adjacent duct 8 by. a 'channelor groove 9 located in the top of the non-conducting member 5, while the .final -duct 8 is connected`with the adjacent duct 7 by a groove 10 also formed in the top of said`,body. -The ends vof the remaining ductsf 8 are connected 'by grooves all denoted by 11 disposed in alternation in the top and bottom of said member 5', ani? by reason of -t-his construction a tortuous or serpentine courseA is provided for 'the 4water to be heated, thel water,' as will hereinafter appear, initially entering the member 5 at the lower end 'of the duct 6 and leaving said member 5 at the lower end of the .duct 7.

. of a resist-ance member, while suchyooils do not [it in said ducts 6 and 7." The duct 6 is Th'e'ducts 6 and 7 and' arep'referably in parallelism and with their co1 me :tingl chan- .'ne1s-iresenta tortuouspassage of which said uctsypl'escnt branches.. Said-ducts, as

will beseen, `are located at different dis tances from the-'axis of1-themember' 5.

Surrounding-tile member 5 is acas'ing 12 which y is geiieraily', although not necessarily,

'made of n xetzil* the casin -extending-above -the upper end of the porco ain member 5 and inaterial. as porcelain. l.Between tli f'jtwfo plates `ltr and the porcelain member -51 I fmay' intel-pose packings'lG while. similarv packingslTmav be' located between the upper plate-15 'and thevl ea 12' and between the lower.V plate 15 and'tl e flan-'ge '14.- I 'Iliet-wo y dates 15,'. .tixedia-nge f 14 'and the porcelain .l 5dr-ft efe." prfereblyjtied vail-.Stilsentially, made of dsksof some insulating l A passage through the porcelain member-f5 I prefer to provide 'a resistance device suc-h as that denoted in a general way by 19. f Thetwo outermost coils -or bends of this re'sisb. ance device 19 are located in the Yfirst and' last 'of the. ducts 8, it being remembered that the ductsr and 7 preferably do .not

contain such who'rls. As will be understood"V .the ducts A6 and do not contain coils of the resistance member 19, but tli ducts 8 do.' N atumllythe ducts 6 and when the valves 30 and 31 are closed are free of water. The ducts 8, however, contain a constant supply of water acting practically in this respect as traps. The water, therefore, constantlycovers the resistance device 19, andowing to this Aconditionsoid resistnee deviceisl prevented from being 'burnedoutwlien the current is turned on. The whorls of the re`-1 sistance coil are connected by transverse p'rtions 20 which lie yin there "tive connecting grooves, 11. tov which r erence has already been made, The terminalsfofthe resistance coil 19 areas shown inFig. 4 connected with the upper end s of the binding,

Coti-'L forming to lthe ports 26 and 27' are valves 30 and 31 which are of plug and tapered typo and which, therefore, do not 'need to be furlherspecifically described. The twovalves 30 and 31 are normally held in their closed position by springs each designated h y 32 und bearing respectively against nuts 33 tapped Vinto the lower pzxrt of the pendent body 2l. The two valves 30 and 31 in the; present case are opened' by being thrust downward, and thc means for vopening the- .suid valves will be hereinafter described.' It.Y will be evident that whenrlietupered portion of the vulve 30 is moved below the channel 24, water cnn flow from snid channel by wav of vthe port 26,' into thev chamher 28,.:ind the Sinne statement. eppliswith respect to the valve. 31 and chamber 29. The .amount of water to be delivered can be gaged by the degree of movement of the two valves which une alternately opened. In the lower pitite l5 is u channel 34, the

The switch which coperates w th the two sets of contacts 46 and 4'? is denoted in a general way by 5 0,l being of; the double armed construction and lic-ing fastened to the shaft 51 mounted in Snc easaig lil. Said shaft also rigidly carries aspur gear lin mesh with a practically similar spur gear 53 and coperative 4esiti' mutilated pinion or segment iico to the .stein 39.

As intimated tie'resistanceshown lirolcenin Fig. 4, the handle ci' liv-:ci l0 at. this time being in its down.- ward position. both valves 30 and 31 being closed. To secure a flow of cold water, the handle l-is swung up to the dotted line posiiioirto the lett in 4,`and onthis motion the. teeth of the mutilated pinion or segment l will not be brought into mesh with the sinn* gear 33. The valve 31, ho\v-' 'ex-er. will no opened by the com 42 so as to position without bringing the. teeth of the mutilated pinion or segment 54 into mesh with those of the spnrgear 53, and I might :nld that wlfeusaid handle is in said upper' position. the :ict-ive part- Of the cam 42 will haw pas-sed ont of engagement with the valu` -ll whfebylthe letter will be closed. 'l`o obtain :i supplyo hot water the handle lo. will be swung eyeito the dotted line. position to the right inFig. 4 and duringthis action the lecthliof the mutilated pinion orv segment 5l willb brought into mesh with the can' gear 53 thereby turning said spur gear 52;, he latterconse uently turning the spur gear TL so as to ca ise the branches or' :ii-nis nl the switch of," to bridge the two sets ni' wnacts 46 "and 4T, vand thereby cause the currentto traverse the whorls of slag resistant-c member 19 and hence heat the ii being understood that when the M sill. thrown to its circuit closing posi- '.I'n; wim il will open the valve 30. To oli' the .suppi of hot water, the lever or bundle l? will be returned to either of llnf liber les :'ilied iliogitions and during die reverse motion of said lever, the switch by the described gearing, is returned to its `circuit opening position. In case there shouldv be any drag from any cause, the spring will positively move said switch toits ineffective or circuit breaking position.
